WW1
Nationalism was the most important cause of ww1 this is because the war was made to show which country was the best. ''Austria was afraid of it's empire breaking up, Which would lead it to losing it's power'' Therefore, it is clear that nationalism was the most important cause of ww1 as the countries wouldn't of gone to war if they did not want to show that they were the best. Nationalism is more important than imperialism (Next paragraph) because none of this would've occurred if nationalism wasn't there.

Nationalism does have a positive effect on the country's pride. So long as it does not morph into fascism, nationalism is a great way to express national pride and honor.
